Kanda River is under the window. 18 years old female student, Mayu, came to stay at the ragged apartment of 4.5 tatami mats. She is 157cm tall and has never measured her three sizes. As soon as she arrives at her room, he puts her big dick in to the root for the first time in her college uniform. The erotic sound of the panting voice of the girl who has not become an adult yet. The secret flesh which comes out from the underwear of white buttocks and pure white which are not rubbed. And the white muddy liquid which overflows from inside. In the latter half, it is a feeling of a masterpiece.
